Overview
This procedure describes the detailed steps to follow to ensure safety when “bar holing” using
a Plunger Bar only. This procedure does not describe how to pinpoint a gas leak or any other
applications using the Plunger Bar. Please follow your utility’s proper procedures and steps for
any other particular application.
WARNING
The Plunger Bar is equipment used to make a gas sampling hole in the
ground. Safe use of the Plunger Bar as explained in this procedure is
paramount. Otherwise, tremendous danger to the life and property of the
operator and his/her surroundings can occur.
Safety
The following personal protective equipment (PPE) is recommended when using the
Plunger Bar:
•
•
•
•
•
Steel-toed shoes
Reflective safety vest
Safety glasses
Hard hat
Work gloves
Some operators may also require additional personal protection equipment.
Prior to Use
• Inspect bar for damage; replace it if not suitable for use.
• Coating damage
• Bent rod
• Movement of rod and piston in handle
• If the rod and piston assembly does not move freely, or you
hear loose pieces
• Condition of ball tip
• Check the guide plug
• Should be threaded securely into the handle
• Should be tight
(Guide plug check)

Bar Hole Procedure
WARNING
When bar holing in areas with poor venting (e.g. wall to wall concrete) or
when gas migration may follow the trench line to a structure, use extreme
caution to avoid hitting the gas pipe and potentially rupturing it. You may be
required to limit the depth of the bar hole or locate the utility line to reduce
the risk of hitting a gas pipe.
WARNING
When driving your bar into the ground, be aware of any undue resistance in
the ground which may be caused by an underground utility. If this happens,
cease pounding immediately.
WARNING
Keep the rod tip on the ground when starting a bar hole.
WARNING
The Plunger Bar is primarily intended for bar holing in soil. Using it to go through
hard surfaces (e.g. concrete, asphalt, road bed, etc.) may require excessive force
which may cause the bar to fail or result in injury. Should the bar become wedged
and stuck in the ground, trying to remove the bar by jerking it may cause bar failure
or injury. Alternative drilling tools should be used for hard surfaces.
• Prior to placing any bar holes, read any signs on the street (such as those
placed by utilities) and look for the presence of any underground structures.
• Look for any underground markers, valve boxes, manhole lids, pedestals,
electric distribution transformers, telephone, cable and electric drops, curb
boxes on the gas and water lines and pre-existing mark outs. This includes
TV cable, street lights, traffic lights, hidden dog fences, sprinkler systems,
heated sidewalks, etc. This list is given just as an example and is not
exhaustive of all the things that could be present underground.
• Never knowingly bar hole over your own underground facilities or those of
another utility.

How to Put Bar Holes Into Place
• Place the end of the rod on the ground at the point where you want the hole,
then position the rod in a vertical position. Raise the handle with one or both
hands, then bring the handle down, allowing the weight of the handle to drive
the rod into the ground. Release your grip slightly at the moment of impact.
Do not try to force the bar into the ground by the strength of your shoulders or
back. Do not have multiple people apply force on the handle to drive the rod. If
ground resistance is too strong to drive the rod, ascertain the reason. Different
equipment may be needed.
• Stand erect with bent knees hold the Plunger Bar away from your face and body.
• Pound the bar down a couple of inches then work bar around in a circular fashion.
• Repeat the process until the desired depth has been reached.
• As the Plunger Bar is driven deeper, bend your knees, not your back.
• Once the bar hole is completed to the desired depth, you can reverse the handle
action to remove the Plunger Bar form the hole. Raise the handle with your
hands, allowing the weight of the handle to pull the rod out of the ground. Be
sure to keep your head clear—people have been known to knock themselves
out by hitting themselves in the chin.
• Check the guide plug frequently during use.
CAUTION
Always keep your back straight, keep the Plunger Bar
handle away from your face and upper body. Keep
knees bent.

Things to Consider
• Some companies limit the maximum depth for bar holing (typically to 18 inches).
This minimizes the potential for injury and damage to the underground utilities.
• When bar holing to classify a leak, our primary focus is the migration of the
gas to underground and above ground structures and buildings; we are not
pinpointing the leak for repair. Please follow your utility’s procedure for
pinpointing and classifying leaks.
• How to carry the bar: the most practical way to carry
the bar is to place the handle on the ground, grasp the
handle about 6” to 8” from the bottom of the handle,
then rest the rod on your shoulder, the bar should be
upside- down at this point. Make certain you grasp the
rod securely and far enough down so that your hand
does not get pinched between the rod and the handle.
By doing this, you have the bar parallel and to one side
of your body, where you can control it. Do not place the
handle over your shoulder with rod behind you. You will
be unable to watch it, and you run the risk of injuring
someone around you.
Conclusion
• Safety is paramount when using the Heath Consultants Incorporated Plunger Bar.
• Review your company’s written procedures regarding required PPE, placement
of bar holes and maximum bar hole depth.
